Great theology is always a kind of giant and intricate poetry, like epic or saga. It is written for those who know the tale already, the urgent messages and the dying words, and who attend to its retelling with a special alertness, because the story has a claim on them and they on it. Theology is also close to the spoken voice. It evokes sermon, sacrament, and liturgy, and of course, Scripture itself, with all its echoes of song and legend and prayer. It earns its authority by winning assent and recognition, in the manner of poetry but with the difference that the assent seems to be to ultimate truth, however oblique or fragmentary the suggestion of it. Theology is written for the small community of those who would think of reading it.
